1 Introduction to the product1.1 Fields of application

Continuously increasing demands on the economic benefit of electric ma‐chines require new problem-solving approaches to fulfill the requirements ondynamic, accuracy and synchronization. Conventional NC-drives, consistingof a rotary electrical motor and mechanical transmission elements like gear‐boxes, belt transmissions or gear rack pinions, cannot fulfill these demandsor, only with high effort.Due to the wide application range of ironless linear motors, medium to midgetmass can be moved and positioned high-dynamically and high-precisely.Based on the above-mentioned advantages, typical applications result for ex‐ample in:● Electronic, placement technology and manufacturing technology● Semi-conductor technology (z.B. wafer inspection and bonding)● Medical technology (e.g. transport of pipettes)● Solar technology (e.g. laser structuring)● Precision and ultra-precision machiningEven in other areas, for example, in machine tool industry, printing industryand especially in measuring technology, the advantages of this technologybecomes important.The ironless drive technology offers a lot of significant advantages in oppo‐site to a ferrous motor, without accepting disturbing ancillary effects like cog‐ging. For this reason, it is the optimum option for many applications.Significant advantages of ironless linear motors are:● Highest dynamic● Excellent control quality and synchronization● No magnetic attractive force, no detent torque● High-precision positioning behavior● Direct power transfer – no mechanical transmission elements like ball

screw, toothed belt, gear rack, etc.● High efficiency - low overhead● Maintenance-free drive (no wearing parts at the motor)● Simplified machine structure

1.3 SetupIronless linear motors MCL consist of the components primary and secondarypart and have an optional Hall unit .The ironless primary part bears the electrically active part of the linear motorwith a winding, cast in plastics. The primary part carrier made of aluminumserves to assemble the primary part and for heat dissipation out of the pri‐mary part. A fastening of an optional Hall unit for position recording is pre‐pared on the primary part. Additionally, a temperature sensor is placed in thewinding. Hall unit and temperature sensor are available for all MCL, exceptfor the smalles frame size.The secondary part consists of an u-shaped iron yoke. The legs of the yokebear permanent magnets and surround the primary part. The line is built withthe secondary parts and can be realized as long as you want.The motor type designation depends on the ironless primary part. The desig‐nation is as follows:● MCL: Motor Coreless Linear● MCL: Motor Coreless Primary part● MCS: Motor Coreless Secondary part

1.4 Comparison ironless with ferreous linear motorsFerreous linear motors use the iron, in which the winding is inserted to bundlethe magnetic flow. Therewith, a very high force density is reached. Act up toa principle, very high magnetic attractive forces exist among the motor com‐ponents (primary and secondary part). These lead to detent force and due tosaturation effecst to other parasitic effects, such as e.g. winding influencesfor ripple of the operation force.No attractive forces exist among primary and secondary part towards ferre‐ous linear motors. Detent forces due to a slotting, existing for ferreous linearmotors are also not created. These aspects and the relatively small movedmass of the primary part allow a vergy high dynamic with high precision atthe same time.Additionally wearing mechanical components are not necessary due to directinstallation into the machine. Due to not existing mechanical elements, abacklash free, with minimum or without hysteresis afflicted drive train, isavailable.

("Protective Extra-Low Voltage") systems. It is allowed to connect devicesequipped with basic insulation (such as programming devices, PCs, note‐books, display units) to these connections. Danger to life, risk of injury by electric shock! High electrical voltage by incor‐rect connection!If extra-low voltage circuits of devices containing voltages and circuits ofmore than 50 volts (e.g., the mains connection) are connected to BoschRexroth products, the connected extra-low voltage circuits must comply withthe requirements for PELV ("Protective Extra-Low Voltage").

3.3.3 Protection against dangerous movementsDangerous movements can be caused by faulty control of connected motors.Some common examples are:● Improper or wrong wiring or cable connection● Operator errors● Wrong input of parameters before commissioning● Malfunction of sensors and encoders● Defective components● Software or firmware errorsThese errors can occur immediately after equipment is switched on or evenafter an unspecified time of trouble-free operation.The monitoring functions in the components of the electric drive and controlsystem will normally be sufficient to avoid malfunction in the connecteddrives. Regarding personal safety, especially the danger of injury and/orproperty damage, this alone cannot be relied upon to ensure complete safety.Until the integrated monitoring functions become effective, it must be as‐sumed in any case that faulty drive movements will occur. The extent of faultydrive movements depends upon the type of control and the state of opera‐tion. Dangerous movements! Danger to life, risk of injury, serious injury or propertydamage!A risk assessment must be prepared for the installation or machine, with itsspecific conditions, in which the components of the electric drive and controlsystem are installed.As a result of the risk assessment, the user must provide for monitoring func‐tions and higher-level measures on the installation side for personal safety.The safety regulations applicable to the installation or machine must be takeninto consideration. Unintended machine movements or other malfunctionsare possible if safety devices are disabled, bypassed or not activated.To avoid accidents, injury and/or property damage:● Keep free and clear of the machine’s range of motion and moving ma‐

chine parts. Prevent personnel from accidentally entering the machine’srange of motion by using, for example:– Safety fences– Safety guards– Protective coverings– Light barriers

● Mount emergency stopping switches in the immediate reach of the oper‐ator. Before commissioning, verify that the emergency stopping equip‐ment works. Do not operate the machine if the emergency stoppingswitch is not working.

● Prevent unintended start-up. Isolate the drive power connection bymeans of OFF switches/OFF buttons or use a safe starting lockout.

● Make sure that the drives are brought to safe standstill before accessingor entering the danger zone.

● Additionally secure vertical axes against falling or dropping after switch‐ing off the motor power by, for example,– mechanically securing the vertical axes,– adding an external braking/arrester/clamping mechanism or– ensuring sufficient counterbalancing of the vertical axes.

● The standard equipment motor holding brake or an external holdingbrake controlled by the drive controller is not sufficient to guarantee per‐sonal safety!

● Disconnect electrical power to the components of the electric drive andcontrol system using the master switch and secure them from reconnec‐tion ("lock out") for:– Maintenance and repair work– Cleaning of equipment– Long periods of discontinued equipment use

● Prevent the operation of high-frequency, remote control and radio equip‐ment near components of the electric drive and control system and theirsupply leads. If the use of these devices cannot be avoided, check themachine or installation, at initial commissioning of the electric drive andcontrol system, for possible malfunctions when operating such high-fre‐quency, remote control and radio equipment in its possible positions ofnormal use. It might possibly be necessary to perform a special electro‐magnetic compatibility (EMC) test.

3.3.4 Protection against electromagnetic and magnetic fields during opera‐tion and mounting

4 Technical data4.1 Explanations about technical data4.1.1 Introduction

All relevant technical motor data as well as the functional principle of this mo‐tors are provided on the following pages in terms of tables and characteristiccurves. The following dependencies are taken into consideration:● Frame size and frame length of the primary part● Winding design primary part● Available power connection or DC bus voltage

All specified data and characteristic curves refer to the followingconditions, unless otherwise specified:● Self-cooling● Installation mode B acc. to Tab. 9-12 on page 131● Keeping installation tolerances acc. tochapter 5.1 "Specifi‐

cations" on page 45● Keeping ambient temperatures acc. to chapter 9.3 "Installa‐

tion altitude and ambient conditions" on page 100● Motor winding temperature ≤110 °C

Specified values in the data sheet are effective values accordingto DIN EN 60034-1. The reference value is a maximum DC busvoltage of 300 VDC at MCP020 ... 070 or 48VDC for MCP015. Re‐sulting data from special motor-controller combinations may differfrom this specified data.

All relationships and data described in the following sections mayonly apply if exclusively primary and secondary parts of the samesize are combined (e.g. MCP015 with MCS015).

4.1.2 Operating behaviorThe characteristic curve “force over speed” is specified as a characteristiccurve The basic parameters and the run of the characteristic curve is definedby the height of the intermediate circuit voltage and by the corresponding mo‐tor specific data, like e.g. inductivity, resistance, force constant and so on. Byvarying the intermediate circuit voltage (different controllers or supply mod‐ules and connection voltages) and different motor windings result in differentcharacteristics result.Furthermore, a continuous force characteristic curve FN for installation modeB (good thermal connection) is shown. The installation modes are describedin Chapter 9.22 .

tion specified in chapter 9.23 .Fig. 4-1: Example motor characteristic curve

For deviating connection or DC bus voltages, the specified char‐acteristic curves can be converted – in linear form – according tothe existing voltages.

The maximal force Fmax is available up to speed vFmax. There, the specifiedvoltage limit is reached due to the DC bus voltage. However, during increas‐ing velocity, the induced voltage of the motor increases. This leads to a ve‐locity-dependend reduced maximum force, as the motor control voltage willbe reduced due to the constant DC bus voltage.The continuous nominal force FN is available up to nominal velocity vN.The maximum velocity vmax is the maximum reachable motor velocity at ap‐propriate UDC up to approximately FN = 0 N.

The reachable motor data are significantly dependent from thethermal coupling of the motor onto the machine (power loss dissi‐pation) and from the used drive controller. The reference quantityfor details of technical data and the presentation of the motorcharacteristic curves is an uncontrolled DC bus voltage of 300VDC from MCP020 up to MCP070 or 48 VDC for MCP015.You will find additional notes about thermal coupling under Chap‐ter 9.22 .Notes about standstill operation in Chapter 9.23 .

5 Dimension sheets5.1 Specifications

Comply with the trademark rights of third parties during assemblyand use of single components delivered by Bosch Rexroth. Forany infringement of the right, the customer is liable for the accru‐ing damage.

5.1.1 Air gap and installation heightTo ensure safe operation and constant force over the entire travel range, anair gap is required between primary and secondary part. For this purpose, theindividual parts of the motor are tolerated accordingly. The distance of themounting surface, the parallelism and the symmetry of the primary and sec‐ondary part of the linear motor in the machine must be within a certain toler‐ance above the entire travel length. Any deformations that result from weight,attractive forces and process forces must be taken into account.

● The specified installation dimensions with respective toleran‐ces must always be complied with over the entire travellength. An insufficient air gap may lead to contact betweenthe primary part and the secondary part and thus to dam‐aged and destroyed motor components.

● Long distances can make is necessary that the contact sur‐faces of the motor components must be directly processedfrom the mounted slide.

For the installation of the motors into the machine structure, Bosch Rexrothspecifies a defined installation position with tolerances. Thus, the specifiedsize and tolerances of the air gap are maintained automatically – even if indi‐vidual motor components are replaced.

5.1.4 Parallelism and symmetry of machine partsBefore primary and secondary part can be mounted, align the parts of themachine. Especially the machine slide is to be brought into a defined positionto the machine bed. When aligning, the installation dimensions and toleran‐ces regarding parallelism and symmetry must be kept.To keep the tolerances, it is necessary that the fastening holes for the pri‐mary part and the threaded holes for the primary and secondary part in themachine are strictly realized according to the dimensions of the particular di‐mension sheets. The alignment of the motor components must be done ac‐cording to Fig. 5-1.You will find further notes regarding assembly of primary and secondary partsin chapter 13 on page 159.

7 Accessories and options7.1 Hall unit7.1.1 General

For control of synchronous motors, the absolute position information regard‐ing a pole pair is required to recognize the position of the permanent magnetsto the motor windings. Only in connection with an electrical commutation off‐set angle to be determined on initial commissioning, the current with correctphase position to the magnetic field can be set via the controller to enablegeneration of a defined force in the dedicated travel direction by the motor.If an incremental length measuring system is used, commutation of the axishas to be performed every time the phase of the drive is step up. This is real‐ized by a drive-internal procedure. Subsequently, the motor power can devel‐op.

The commutation is determined automatically during the phasestep up by the Hall unit. Therefore, no power switch-on is neces‐sary (no motor movement).

The Hall unit offers special advantages, for commutation of linear motors, forexample ...● in gantry arrangement ● at vertical axes● in mechanically secured state,● that must not be moved for safety reasons during commutation.

7.1.2 Hall unit functionThe Hall unit (analog or digital) serves for motionless commutation of the line‐ar motor in connection with an incremental measuring system. For IndraDriveCs, the motor commutation is performed automatically on phase switching tooperating mode. For this, motion is not required. The motor may also be in afixed stop or positioned at the end of the travel length (end stop), for exam‐ple.Rexroth linear motors of MCL020 ... 070 series can be ordered according tothe motor type code with or without Hall unit (seechapter 6.1.2 "Type codesprimary part MCP" on page 61).

Independent from the origin order, primary parts of frame size020 ... 070 can be converted or upgraded with a separately order‐able Hall unit.

8.3 Sensors8.3.1 Connection temperature sensor

All primary parts - except frame size MCP015 - are equipped with a PTC tem‐perature sensor KTY84-130. The temperature sensor is fixed within the motorwinding and serves for winding temperature measuring. The temperaturesensor itself offers no safe protection of the winding from thermal overload.The thermal monitoring of the motor must additionally be done via a workingtemperature modell in the controller.Heed the right polarity of the connection wires when connecting theKTY84-130 . The wire designation can be found under Fig. 8-1.For additional information on the temperature sensor, please refer to chapter9.10 "Motor temperature monitoring" on page 107.

● Temperature sensor KTY84-130 is a component that mightby damaged by ESD! For this reason, the wires of the sen‐sor are protected by a protective foil at the connection cable.Before connecting the sensor, take measures regardingESD protection.( ESD = electrostatic discharge).

● The used temperature sensors are double or reinforced in‐sulated according to DIN EN 50178, so separation exists ac‐cording to DIN EN 61800-5-1.

8.3.2 Connection Hall unitMotors with Hall unit have an additional cable to connect the sensor. This ca‐ble is beside the connection cable for the power. After motor installation, thecable of the Hall unit can be shortened to the required length and be assem‐bled with a D-sub connector, 9-pole (pin), for example. Also refer to Chap.8.3.3 .

9 Application and construction instructions9.1 Mode of functioning

The force generation for an ironless synchronous-linear motor, is the sameas the torque generation at rotary synchronous motors. The ironless primarypart (active part) has a winding; the secondary part (passive part) has perma‐nent magnets.Both, the primary part and the secondary part can be moved.Realization of any traverse path lengthcan be done by stringing together sev‐eral secondary parts.

Axis construction The MCL motor is a kit motor. The components primary and secondarypart(s) are delivered separately and completed by the user via linear guideand the linear measuring system. They are mounted into the machine or sys‐tem.The construction of an axis fitted with a linear motor normally consists of● Primary part with Hall unit● one or more secondary parts with permanent magnets● Length measuring system● Linear guide● Energy flow● Slide or machine constructionFor force multiplication can be two or more primary parts mechanically cou‐pled, arranged in-line. For further information see chapter 9.13.2 "Severalmotors per axis" on page 113.

Only the primary and the secondary part(s) belong to the scope ofdelivery of the motor. Linear guide and length scale as well as fur‐ther additional components have to be made available by theuser.

9.2 Motor design9.2.1 Design primary part

The primary part consists of an u-shaped aluminum primary part carrierwhich bears the coil body and is molded with plastic resin. This mold servesfor mechanical property of the MCP. It is no protection against humidity, for‐eign bodies or touch of electrically active parts. Due to the mold process,sometimes small blowholes can occur on the surface of the mold. They arenot relevant for the function and mechanical property of the motor. The motorcooling happens due to the thermal couplingof the primary part on the ma‐chine and via the natural convection.

9.7 Magnetic fieldsDuring operation of electric motors, electromagnetic fields are generated atlive components and connection lines of these motors. The secondary partsequipped with permanent magnets of synchronous linear motors and rotorsof synchronous kit motors are magnetically not shielded and permanentlygenerate a static magnetic field (DC field) even if not activated. This is indica‐ted by a warning label attached to each package with open permanent mag‐net components.if all regulations and safety measures are complied with, synchronous kit mo‐tors with open permanent magnet components do not cause any inadmissiblehazards. As of a distance of approx. 100 mm to the surface of open perma‐nent magnet parts, there is practically no effective magnetic attraction of fer‐romagnetic parts. However, for people with implants, a minimum safety dis‐tance of 1 meter (1000 mm) is recommended.Depending on the operating location, transport ways and storage of the ma‐chine and its components, local regulations and laws apply and have to becomplied with during construction, transport and operation of the machine.

9.9 Thermal behaviorPower loss The rated feed force of a synchronous linear motor can be achieved is mainly

determined by the power loss PV produced during the energy conversionprocess. The power loss fully dissipates in form of heat. Due to the limitedpermissible winding temperature it must not exceed a specific value.

The allowed winding temperature of the motors is 130 °C.

The total loss of synchronous linear motors are significantly defined by theshort-circuit loss of the primary part.

PV Total loss in WPVI Short-circuit loss in WI Current in motor cable in AR12 Electrical resistance of the motor at 20 °C in Ohm (see Chapter

4 ”Technical data”)fT Factor temperature-related resistance raiseΔT Temperature increase in Kα20 Temperature coefficient of cupper in 1/KFig. 9-6: Power loss of synchronous linear motors

When you determine the power loss according to Fig. 9-6 youmust take the temperature-related rise of the electrical resistanceinto account. At a temperature rise of 100 K (from 20 °C up to120 °C), for example, the electrical resistance goes up by the fac‐tor fT = 1.39.

Thermal time constant The temperature variation vs. the time is determined by the produced powerloss and the heat-dissipation and –storage capability of the motor. The heat-dissipation and –storage capability of an electrical machine is (combined inone variable) specified as the thermal time constant.The following figure (Fig. 9-7) shows a typical heating and cooling process ofan electrical machine. The thermal time constant is the period within which63% of the final over temperature is reached.Together with the duty cycle, the correlation to Fig. 9-8 and Fig. 9-10 areused to define the operating modes, e.g. acc. to DIN EN 60034-1.

9.10 Motor temperature monitoringThe motor temperature is monitored by two systems that are operated inde‐pendently of each other● Temperature sensor (motor)● Temperature model (controller)and ensures thus the best protection of motors against irreversible damageby thermal overload.Primary parts of frame sizes MCP020 ... 070 are standardly fitted with an in‐tegrated temperature sensor (KTY84-130) for measuring the winding temper‐ature. An all-phase monitoring is impossible with only one KTY. Thus, it ispossible that a phase in standstill operation with continuous currents are nearthe rated current, which is monitored by a KTY, is thermally overloaded, de‐spite the KTY only displays measuring values < 110°C. The exclusive use ofthe KTY for temperature monitoring means no sufficient motor protection forthe primary parts.

A possible form of an additional motor protection is, to limit themotor current to 87% of the rated current at low velocity (< 1 m/min) or at movement via a short traverse path (< 2 · tP).

The Rexroth IndraDrive control devices monitor the functionality of the tem‐perature sensors. For more information, please refer to the functional de‐scription for IndraDrive controllers.

KTY84-130 is an ESD sensitive device! For this reason, the wiresof the sensor are protected by a protective foil at the connectioncable. Before connecting the sensor, take appropriate measuresfor ESD protection ( ESD = electrostatic discharge).To connect temperature sensors heed the details under chapter8.3.1 "Connection temperature sensor" on page 90.

9.11 Feed force at reduced covering between primary and secon‐dary part

When moving in the end position range of an axis, it can be necessary thatthe primary part moves beyond the end of the secondary part. This results ina partial coverage between primary and secondary part.If primary and secondary part are only partially covered, a reduced feed forceand attractive force results.

Inserted force reduction Outside the beginning and end areas (sR1 or sR2), the reduction of the force islinear with the reduced overlap area.The following diagram illustrates the correlation between the coverage be‐tween primary and secondary part and the resulting force reduction.

If a Hall unit is used for commutation, the primary part on the cable output side mustbe completely within the secondary part. During operation, which is normally withoutanalysis of the Hall unit, the primary part can be operated as described under "with‐out Hall unit".

Tab. 9-6: Partial coverage vs. installation positionThe partial coverage of primary and secondary parts must not be used incontinuous operation since there is an increased current consumption of themotor due to control strategies. Instabilities in the control loop can be expec‐ted from a certain reduction of the degree of coverage onwards.

9.12 Requirements on the machine design9.12.1 General

Derived from design and properties of linear direct drives, the machine con‐struction must meet various requirements. For example, minimizing of mov‐ing masses with simultaneous high rigidity should be realized.

9.12.2 Mass reductionTo ensure a high acceleration capability, the mass of the moved machine ele‐ments must be reduced to a minimum. This can be done by using materialsof a low specific weight (e.g. aluminum or compound materials) and by de‐sign measures (e.g. half-timbered construction).If there are no requirements for the highest acceleration, even relative bigmass can be moved. A very rigid coupling of the motor to the weight is a pre‐condiiton.

9.12.3 Mechanical rigidityIn conjunction with the mass and the resulting resonant frequencies, the ri‐gidity of the individual mechanical components within a machine chiefly de‐termines the quality a machine can reach. The rigidity of a motion axis is de‐termined by the overall mechanical structure. The goal of the constructionmust be to obtain an axis structure that is as compact as possible.

Natural frequency The increased loop bandwidth of linear drives required higher mechanicalnatural frequencies of the machine structure in order to avoid the excitation ofvibrations.To ensure a sufficient control quality, the lowest natural frequency that occursinside the axis should not be less than approximately 200 Hz. The natural fre‐quencies of axes with masses, that are not constantly moving (e.g. due towork pieces that must be machined differently), change, so that the natural

frequency is reduced as the mass increases. Mechanically coupled axes With the stiffness of kinematically coupled axes, it should be taken into ac‐

count that the flexibility of the axes - both the mechanical and the controlcomponents - add up.If several axes must be coupled cinematically in order to produce path mo‐tions (e.g. cross-table or gantry structure), the mutual effects of the individualaxes on each other should be minimized. Thus, cinematic chains should beavoided in machines with several axes. Axis configurations with long projec‐tions that change during operation are particularly critical.

Reactive forces Initiated by acceleration, deceleration or process forces of the moved axis,reactive forces can deform the stationary machine base or cause the fixedmachine base body to vibrate.

9.12.4 Protection of the motor installation spaceDue to protection mode IP00 of the motor components, the protection of themotor installation space need especial observance. To avoid that dirt comesinto the air gap between primary and secondary part (e.g. due to any kind ofresidues, dust, etc.) during motor operation, the motor installation space mustbe designed according to the environmental conditions. The motor installationspace must be designed in such a way, that the protection class IP65 accord‐ing to DIN EN 60034-5 equivalent environmental conditions are ensured (seechapter 9.5 "Type of protection" on page 102).Heed appropriate protection measures when designing the machine con‐struction. If dirt gets between the motor components due to insufficient pro‐tection measures, during operation this can lead to...● an increased heat introduction due to friction between the motor compo‐

nents. Thereby, temperatures can arise, which can cause a motor dam‐age.

● Due to the high mechanical force effectgrinding traces and /or scratch-formation on the motor components can result in the destroying of cast‐ing compounds on the primary part, to motor breakdown,, among oth‐ers.

Please note that dirt can also enter indirectly into via compressed air or dueto other machine parts (e.g. grease of the guides). This must be prevented.Make sure by regularly maintenance of the safety measures that their func‐tion is still kept and the motor components could not be damaged.

9.13 Arrangement of motor components9.13.1 Single arrangement

The single arrangement of the primary part is the most common arrange‐ment. One or more primary parts can be controlled independently of eachother. In such an arrangement, the length measuring system can also beequipped with two or more scanning heads.

Gantry arrangementIf different load conditions occur during operation, both locally and temporally,and a sufficient rigidity between the motors cannot be ensured, the operationshould be planned with two linear scales and drive controllers (Gantry ar‐rangement). This is frequently the case with axis in a Gantry structure, for ex‐ample.

Within a Gantry arrangement, even parallel connected motors canbe used.

Double comb arrangement (Gantry)Within a Gantry arrangement, the primary parts in feed direction can be me‐chanically coupled and arranged in the form of a double comb arrangement.

① Control unit② Controller (2 pcs.)③ Length measuring system (2 pcs.)Fig. 9-26: Gantry arrangement (double comb)With Gantry arrangements it must be remembered that the motors may bestressed asymmetrically, although the position offset is minimized. As a con‐sequence, this permanently existing base load may lead to a generally higherstress than a single arrangement. This must be taken into account when thedrive is selected.

The asymmetric capacity can be reduced to a minimum by exact‐ly aligning the length measuring system and the primary and sec‐ondary parts to each other, and by an internal axis error correc‐tion.

Arrangement of primary parts in a row (Gantry)Primary parts in feed direction can also be arranged in a row, mechanicallycoupled.

9.13.3 Arrangement of secondary partsDuring assembly, you must not heed the arrangement of the secondary parts.Due to construction of MCS, a "polarity reversal" - arrangement of severalsecondary parts within a path is prevented. The order of magnetization is un‐changed by a 180° - rotation of secondary parts.Please observe the notes in chapter 13.4 "Air-gap, parallelism and symmetryof the motor components" on page 160 and chapter 13.5 "Fastening secon‐dary part" on page 161 about alignment and fastening of secondary parts.

9.13.4 Vertical axis

Uncontrolled movements! Risk of injuries!CAUTION

Motors in vertical axes are not self-locking when de-energize. Prevent a sink‐ing of the axis with appropriate holding devices.

● On vertical axis, the use of an absolute measuring system isrecommended.

● Incremental measuring systems can only be used, if a Hallunit is additionally used beside the holding device.

Weight compensation An additionally used weight compensation ensures that the motor is not ex‐posed to an unnecessary thermal stress that is caused by the holding forcesand the acceleration capability of the axis is independent of the motion direc‐tion. The weight compensation can be pneumatic or hydraulic. Weight com‐pensation with a counterweight is not suitable since the counterweight mustalso be accelerated.

9.14 Length measuring system9.14.1 General

A linear measuring system is required for measuring the position and the ve‐locity. Particularly high requirements are placed upon the linear scale and itsmechanical connection. The length measuring system is used for high-resolu‐tion position recognition and the determination of the actual velocity.

The necessary length measuring system is not in the scope of de‐livery of Bosch Rexroth and has to be provided and mounted fromthe machine manufacturer themselves(tab. 9-10 "Manufacturersof length measuring systems" on page 121).

Fig. 9-28: Classification of linear scalesParticularities of synchronous line‐

ar motorsIt is necessary at synchronous linear motors to receive the position of the pri‐mary part relating on the secondary part by return after start or after a mal‐function (pole position recognition). Using an absolute linear scale is the opti‐mum solution here.

9.14.2 Selection criteria for length measuring systemGeneral

Depending on the operating conditions, open or encapsulated linear scaleswith different measuring principles and signal periods can be used. The se‐lection of a suitable linear scale mainly depends on:● The maximum feed rate (model, signal period)● The maximum travel range (measuring length, model)● If applicable, utilization of coolant lubricants (model)● Incidental dirt, chips, etc. (frame size)● the accuracy requirements (signal period)

Manufacturers of length measuring systemsThe following selection is exemplary and does not claim to be complete. Youcan also use products from other manufacturers, according to the encoder in‐terface of the used controller.

9.15 Linear guiding systemsLinear guiding systems for linear motors are, depending on the motor ar‐rangement, necessary due to feed and process forces as well as the speedsachievable today. The used linear guiding system must be able to adjustprocess and acceleration force.Depending on the application, the following linear guides are employed:● Ball or roll rail guides

● Slide ways● Hydrostatic guides● Aerostatic guidesThe following requirements should be taken into account when a suitable lin‐ear guide system is selected:● High accuracy and no backlash● Low friction and no stick-slip effect● High rigidity● Steady run, even at high velocities● Easy mounting and adjustment

Manufacturer Linear guiding systems are not in the scope of delivery of the mo‐tor and must be ordered separately. The selection of a suitablelinear guiding system is in the sole responsibility of the machinemanufacturer. When selecting linear measuring systems pleaseobserve that this system uses sinusoidal instead of rectangularoutput signals. With sinusoidal output signals, a significantly high‐er position resolution and better position accuracy is reached viaspecial evalutation revolution of our controllers.

9.17 End position shock absorber

Damage on machine or motor componentswhen driving against hard stop!

WARNING

⇒ Use suitable energy-absorbing end position shock absorber⇒ Adhere to the specified maximum decelerations

Suitable energy-absorbing end position shock absorber must be provided inorder to protect the machine during uncontrolled coasting of an axis.If the maximum deceleration is exceeded, this can cause the primary part tocome loose and damage the engine components.

● When moving against a fixed stop, the maximum permissibledeceleration must be limited to 250 m/s² by a suitable ener‐gy-absorbing end position damper.

● The necessary spring excursion of the shock absorbersmust be taken into account when the end position shock ab‐sorbers are integrated into the machine (in particular whenthe total travel length is determined).

9.18 Axis cover systemsDepending on the application, design, operational principle and features ofsynchronous linear motors, the following requirements on axis cover systemsapply:● High dynamic properties (no overshoot, little masses)● Accuracy and smooth run● Protection of motor components against chips, dust and foreign objects

(in particular ferromagnetic parts),● Resistance to oil and coolant lubricants● Robustness and wear resistanceDifferent covering systems can be used, like bellow covers, telescopic coversor roller covers. A suitable axis cover system should be configured, if possi‐ble, during the early development process of the machine or system – sup‐ported by the corresponding specialized supplier.

9.20 Deactivation upon EMERGENCY STOP and in the event of amalfunction

9.20.1 GeneralDeactivation of an axis equipped with MCL motor, can be initiated by● EMERGENCY STOP,● Drive fault (e.g. response of the encoder monitoring function) or● Power outage In the options for deactivation of MCL motors in case of malfunction, a dis‐tinction must be made between● Deactivation by the drive,● Deactivation by a master control and● Deactivation by a mechanical braking device.

9.20.2 Deactivation by the driveAs long as there is no fault or malfunction in the drive system, shutdown bythe drive is possible. The shutdown possibilities depend on the occurred driveerror and on the selected error response of the drive. Certain faults (interfacefaults or fatal faults) lead to a force disconnection of the drive.

Death, serious injuries or damage to equip‐ment may result from an uncontrolled coast‐ing of a switched-off linear drive!

WARNING

⇒ Construction and design according to the safety standards⇒ Protection of people by suitable barriers and enclosures⇒ Using external mechanical braking facilities⇒ Use suitable energy-absorbing end position shock absorber

The parameter values of the drive response to interface faults and non-fatalfaults can be selected. The drive switches off at the end of each fault re‐sponse.The following fault responses can be selected:0 – Setting velocity command value to zero1 - Setting force command value to zero2 - Setting velocity command value to zero with command value ramp and fil‐ter3 - Retraction

Please refer to the corresponding firmware function descriptionfor additional information about the reaction to faults and the rela‐ted parameter value assignments.

9.20.3 Deactivation by a master controlDeactivation by control functions

Deactivation by the master control should be performed in the followingsteps:

1. The machine PLC or the machine I/O level reports the fault to the CNCcontrol

2. The CNC control deactivates the drives via a ramp in the fastest possi‐ble way

3. The CNC control causes the power at the power supply module to beshut down.

Drive initiated via the control shutdownDeactivation via means of drive functions should be performed in the follow‐ing steps:

1. The machine I/O level reports the fault to the CNC control and SPS2. The CNC control or the PLC resets the controller enabling signal of the

drives. If SERCOS interface is used, it deactivates the ”E-STOP” inputat the SERCOS interface module.

3. The drive responds with the selected error response.4. The power at the power supply module must be switched off 500 ms af‐

ter the controller enabling signal has been reset or the ”E-Stop” inputhas been deactivated.

The delayed power shutdown ensures the safe shutdown of thedrive by the drive controller. With an undelayed power shutdown,the drive coasts in an uncontrolled way once the DC bus energyhas been used up.

9.20.4 Deactivation via mechanical braking deviceShutdown by mechanical braking devices should be activated simultaneouslywith switching off the power at the power supply module. Integration into theholding brake control of the drive controllers is possible, too. The followingmust be observed:● Braking devices with electrical 24V DC control (electrically-released)

and currents < 2 A can directly be triggered.● Braking devices with electrical 24V DC control and currents > 2 A can

be triggered via a suitable protection.Once the controller enabling signal has been removed, the holding brakecontrol has the following effect:● Fault reaction ”0”, ”1” and ”3”.

The holding brake control drops to 0 V once the velocity is less than 10mm/min or a time of 400 ms has elapsed.

● Fault reaction "2":The holding brake control drops to 0 V immediately after the drive ena‐bling signal has been removed.

9.20.5 Response to a power outageIn order to be able to shut down the linear drive as fast as possible in theevent of a power outage,

● either an interruption-free power supply or● additional DC bus capacities (capacitors), and /or● mechanical braking facilitiesmust be provided.

Determining the required addition‐al DC bus capacity

Additional capacities in the DC bus represent an additional energy store thatcan supply the brake energy required in the event of a power outage.

The control voltage must be available even at a power failure forthe time of braking! If needed, buffer the control voltage supply orfeed the control voltage from the DC intermediate circuit if possi‐ble!

The additional capacity required for a deactivation upon a mains failure canbe determined as follows:

Cadd Required additional DC bus capacitor in mFm Moved mass in kgvmax Maximum velocity in m/sUDCmax Maximum DC bus voltage in VUDCmin Minimum DC bus voltage in VFmax Maximum braking force of the motor in NkFN Motor constant (force constant) in N/AR12 Winding resistance at 20 °CFR Friction force in NFig. 9-30: Determining the required additional DC bus capacitorPrerequisites:- final velocity = 0- velocity-independent friction- constant deceleration- winding temperature 135 °C

The maximum possible DC bus capacity of the employed powersupply module must be taken into account when additional ca‐pacities are used in the DC bus. Do not initiate a DC voltageshort-circuit when additional capacitors are employed.

9.20.6 Short-circuit of DC busMost of the power supply modules of Bosch Rexroth permit the DC bus to beshortened when the power is switched off, which also establishes a short-cir‐cuit between the motor phases. When the motor moves, this causes a brak‐ing effect according to the principle of induction; thereby the motor phasesare short-circuited. However, the achievable braking force is not very highand also depends on the velocity. The DC bus short-circuit can therefore onlybe used to support existing mechanical braking devices.

9.21 Position and velocity resolution9.21.1 Drive internal position resolution and position accuracy

In linear direct drives, a linear scale is used for measuring the position. Thelinear scale for linear motors supply sinusoidal output signals. The length ofsuch a sine signal is known as the signal period. It is mainly specified in mmor µm.With the drive controllers from Bosch Rexroth, the sine signals are amplifiedagain in the drive (see Fig.9-32). The drive-internal amplification also de‐pends on the maximum travel area and the signal period of the length meas‐uring system. It always employs 2n grid points (e.g. 2048 or 4096).

9.22 Thermal connection - Installation modesAn effective heat loss dissipation is a prerequisite for achieving the specifiedmotor data. The amount of heat loss in the motor is largely determined by theutilization rate of the motor. How well or how quickly the heat loss can be dis‐sipated determines the performance of the motor.If the heat of the motor cannot be sufficiently dissipated by means of naturalconvection, the heat introduction via the contact surfaces into the machineconstruction is increased. Particularly high heat dissipation is achieved if the

MCL Ironless Linear Motors 129/197

Application and construction instructions

R911330592_Edition 06 Bosch Rexroth AG

Page 138: MCL - Bosch Rexroth

contact surfaces of the primary and secondary parts are combined with ahighly heat-dissipating machine construction.In this connection, please observe that an increased heat introduction intothe machine construction has a negative impact on the achievable accuracy.During design of a system with maximum accuracy, the operating tempera‐ture of the motor winding is decisive.With increasing winding temperature, the emitted heat of the machine is alsoincreased. If the temperature level of the machine has to be kept at a con‐stant level, the motor should be sufficiently dimensioned or equipped withmachine-side cooling.

If the contact surfaces of the motor components, particularly ofthe primary part, are made of a material with low heat conductivity(e.g. plastic), a reduction in motor performance has to be expec‐ted.In general, the heat dissipation must be increased proportionallywith the size and frame length and the respectively higher powerloss of the motor if the same utilization capacity of the motor is tobe achieved.For this reason, observe maximum heat dissipation of motor com‐ponents when designing the machine. Only this way optimum dis‐sipation of the emitted heat of the motor via the surrounding ma‐chine components can be ensured.

The following specifications serve as reference to estimate the required mo‐tor performance data depending on the thermal connection of the motor. Theillustrated installation modes can be selected and taken into account for mo‐tor controller dimensioning in IndraSize and for commissioning in IndraWorks.

Installationmode Schematic illustration Description

A

Installation mode A requires good thermal connection of the motor in com‐bination with additional cooling, e.g. by using a fan or by cooling the con‐tact surfaces. Regarding the structure of the contact surfaces at the ma‐chine, a metal surface with high conductivity is required.

B

Installation mode B requires good thermal connection of the motor to themachine. Regarding the structure of the contact surfaces at the machine,a metal surface with high conductivity is required. The technical data forthis installation mode is specified in chapter 4 "Technical data" on page21.

C

Installation mode C assumes that a motor component (primary or secon‐dary part) is thermally isolated and the other components must be well-conductively connected to the machine. In this case, reckon with a per‐formance reduction of the motor due to moderate heat dissipation

D

Installation mode D assumes that both motor components (primary andsecondary part) are connected to the machine in a thermally isolated way.This mode of assembly is the worst case and it must be reckoned with asignificant disability of the motor.

9.23 Operation at or near motor standstillIn the motor is to be operated at standstill or close to standstill, special condi‐tions apply. For means of simplification, this operation is indicated as stand‐still operation in the following. The absolute standstill operation is marked bythe following aspects:● The duration of the standstill operation is longer than 10 % of the re‐

spective thermal time constant Tth

● Motor does not move● Motor performs only very small strokes (≤ 2 * Τp)● Motor moves only at very low frequency (f ≤ 0.1 Hz)Due to the 3-phase system, during standstill operation in one of the threephases there is always an instantaneous value of the current, the amount ofwhich is higher than the permissible continuous current. Does the currentflow continuously, the motor will overheat and be thermally damaged. Alsorefer to chapter 9.10 "Motor temperature monitoring" on page 107). Thepeak value of the instantaneous current is equal with the amplitude of the si‐nusoidal assumed phase current. Its value is higher by root 2 than the effec‐tive value of the continuous current (IN). The power loss PV, created in thecoil, is calculated using

A possible form of an additional motor protection is the limi‐tation of the motor current to 87% of the nominal current.

By means of path function,the calculation of velocity, acceleration and force can be done. Standard soft‐ware (such as MS Excel or MathCad) can be used for calculating the re‐quired variables, even with complex motion profiles.

The following chapter provides a more detailed correlation for tra‐pezoidal, triangular or sinusoidal speed curves.

For dimensioning of linear motor drives, take the moving mass ofthe motor components into consideration (in particular in case oflow load inertia). However, the moving mass is only known afterthe motor has been selected. For this reason, an assumptionmust first be made and checked again after the motor has beenselected.

11.3 Duty cycle and feed force11.3.1 General

The relative duty cycle ED specifies the duty cycle percentage of the loadwith respect to a total duty cycle time, including idle time. The thermal loadcapacity of the motor limits the duty cycle. Loading the motor with a continu‐ous nominal force is possible during the entire duty cycle time. To avoid ther‐mal overload at motors with higher feed forces reduce the duty cycle at F >FdN (see fig. 11-20 "Correlation between duty cycle and feed force." on page149).

Fig. 11-20: Correlation between duty cycle and feed force.

11.3.2 Determining the duty cycleDue to the linear correlation of force and current, the approximate determina‐tion of the relative duty cycle EDideal is performed via the correlation:

11.4 Determining the drive power11.4.1 General

To size the power supply module or the mains rating, you must determine therated (continuous) and maximum power of the linear drive.

Take the corresponding simultaneity factor into account when de‐termine the total power of several drives that are connected to asingle power supply module.

11.4.2 Continuous powerThe continuous power corresponds to the sum of the mechanical and electri‐cal motor power.

data”)Fig. 11-23: Continuous power of the linear motor

When reducing the continuous nominal force, the electric continu‐ous power is also reduced (seefig. 11-23 "Continuous power ofthe linear motor" on page 150).

11.5 Energy regenerationCompared with rotary servomotors, the energy of a linear motor during decel‐eration is lower. The translational velocity of a linear motor is usually muchlower than the circumferential speed of a rotary servomotor.The regenerative power of a synchronous linear drive results from the energybalance during braking and can be estimated as follows for dimensioning ad‐ditional braking resistors or regenerative supply units:

PR Energy regeneration during a braking phase in WPRavg Average energy regeneration over total cycle duration in Wm Moved mass in kgv Maximum velocity in m/stb Braking time in sFR Friction force in NR12 Winding resistance of the motor at 20°C in Ohm (see Chapter

Constant decelerationFinal velocity = 0

If the determined regenerative power according to Fig. 11-27 isnegative, no energy is fed back, i.e. energy must be supplied tothe motor during braking.

11.6 EfficiencyThe efficiency of electrical machines is the ratio between output and inputpower and, in the case of linear motors, is determined by the application-de‐pendent travel speeds and forces and the corresponding motor losses.The motor efficiency can be determined or estimated with the help of fig.11-28 "Efficiency determination for linear motors" on page 153.

13 Assembly13.1 Basic precondition

The following points must be considered or checked before starting the as‐sembly work:● Observe of the necessary installation sizes (see chapter 5.1 "Specifica‐

tions" on page 45)● Machine construction fulfills the requests for mounting (stiffness, attrac‐

tive force, feed and acceleration force, etc.) and is prepared for installa‐tion of the motor components.

● Clean screw-on surfaces between machine and motor components● Installation of motor components by skilled personnel only● Compliance of danger and safety notes is guaranteed.

13.2 Arrangement of motor componentsDuring machine planning, observe and specify the position of the motor com‐ponents in the machine. All fixtures and screw-on surfaces must be preparedfrom the machine manufacturer for installation of the motor components.Basically, no limitations about arrangement of the motor components exists.It can be an advantage to mount the secondary part sidewards (see fig. 13-1"Arrangement of motor components within ready-to-mount compact moduleCKL of Rexroth" on page 159) or downwards toppled that dirt, residuesa.s.o. can drop into the air gap between primary and secondary part fromabove. In this content, please observe the notes under chapter 9.12.4 "Pro‐tection of the motor installation space" on page 112 on how the installationspace must be created to optimally protect the motor components. The fol‐lowing figure shows a possible motor assembly. Dependend from the applica‐tion, another arrangement can be preferred.

13.3 Installation of motor componentsThe order of installation of motor components is depending on the machineconstruction or the available space in the machine. Also, the arrangement ofthe motor components plays a significant role.In the following assembly example, always motor setup in single arrangementis assumed.● Possibility A

First, determine the secondary parts. Then, insert the primary part later‐ally into the secondary parts and fasten it on the machine. MCP015 pri‐mary parts can also be mounted from above into the secondary part dueto their design (T-shape).

● Possibility BInitially assemble only one secondary part. Insert the primary part on thefront side (or MCP015 from above) into the secondary part and fasten iton the machine. Then, mount the remaining secondary parts.

● Possibility CFirst, mount the primary part and afterwards the secondary part.

13.4 Air-gap, parallelism and symmetry of the motor componentsParallelism and symmetry When mounting primary and secondary parts, their position is specified by

the holes or threads within the machine slide and within the machine bed.Due to the clearance, which exists within the holes of the screw connections,the motor components must be adjusted correctly acc. to fig. 13-2 "Aligningthe motor components" on page 160 before the screws are tightened. Thiscan be done via pressing the motor components on the screw-on surfacesand stop faces. If all installation dimensions tab. 5-1 "MCL015 Installation di‐mensions and tolerances" on page 46Installation dimensionstab. 5-2 "Instal‐lation dimensions and tolerances MCL020 ... 070" on page 47were adheredto, the correct arrangement of both motor components to each other results.

Air gap Motor damage due to insufficient air gap be‐tween primary and secondary part!

NOTICE

After assembly, check the free movement of the motor components to eachother immediately. Therefore, move the versatile motor components by handover the complete travel length. The versatile motor components must befreely movable at each position over the total travel length - without any con‐tact to fixed motor components. This check can detect faulty assembly in time(e.g. dirt under the assembly surfaces, faulty installation dimensions, insuffi‐cient machine rigidity etc.).

13.5 Fastening secondary partObserve absolute cleanness during assembly. No dirt should exist on thescrew-on surface and stop faces and no dirt or other parts (e.g. screws,washers, etc.) should reach the area of magnetic pull on the secondary part.Any kind of foreign bodies in this area could damage the primary or secon‐dary part at the first traverse of the motor components.

● For safety reasons, the user or machine manufacturer isNOT allowed to dismount the secondary part in its separateparts!

● To fasten the secondary parts, it is only allowed to use new,unused screws.

● After aligning, tighten all screws with the specified tighteningtorque (seeChapter 13.4 ). Additionally secure the screwconnection with Loctite 243.

● After assembly, check if any foreign bodies exist in the sec‐ondary part.

The secondary parts can be connected with the machine via two differentways.

① Fastening type variant 1② Fastening type variant 2Fig. 13-3: Secondary part fastening types The screw-on surfaces and stop faces must be cleaned and be free of greasebefore the secondary parts can be screwed on the machine construction.

14 Commissioning, operation and maintenance14.1 General

In some points, commissioning of linear motors is different in comparison torotary servo motors. For commissioning of synchronous linear motors, the fol‐lowing points must be observed in particular:

Parameters Synchronous linear motors are kit motors whose single components are di‐rectly installed into the machine by the manufacturer – completed by an en‐coder system. As a result, kit motors do not feature any data memory to pro‐vide motor parameters, standard controller settings, etc. All parameters mustbe manually entered or loaded to the drive during commissioning. TheIndraWorks commissioning program provides all Rexroth motor parameters.

Controller optimization The procedure for controller optimization (current, velocity and position con‐troller) at linear direct drives corresponds to the procedure for rotary servodrives. Only the setting limits of linear drives are higher. For example, this en‐ables setting up to 10 times higher kv factors at linear direct drives in compar‐ison to rotary servo drives. However, this requires a respective machine con‐struction (see chapter 9.12 "Requirements on the machine design" on page110).

Moving masses With controlled rotary servo drives, there are control limitations in the ratio ofmotor moment of inertia to load moment of inertia. This restriction does notapply for direct drives with linear motors: The moved external load dependson load of the motor itself.

Encoder polarity The polarity of the actual velocity (length measuring system) must complywith the force polarity of the motor. Before commutation adjustment, this rela‐tion must be established.

Commutation adjustment It is necessary at synchronous linear motors to receive the position of the pri‐mary part relating on the secondary part by return after start or after a mal‐function. This is referred to as pole position detection or commutation adjust‐ment. This means that the commutation adjustment is the establishment of aposition reference to the electrical or magnetic model of the motor. Commuta‐tion adjustment can only be made after installation of motor components andthe length measuring system. The commutation adjustment method dependson the measuring principle of the length measuring system.

14.2 General requirements 14.2.1 General

The following requirements have to be met to ensure successful commission‐ing:● Compliance with safety-related guidelines and instructions● Check of electrical and mechanical components for reliable functioning● Availability and provision of required tools● Adherence to the commissioning procedure described below

14.2.2 Checking all electrical and mechanical componentsCheck all electrical and mechanical components prior to commissioning andpay particular attention to the following issues:

wareThe motors can be commissioned either directly via an NC terminal or viaspecial commissioning software. The IndraWorks commissioning software al‐lows menu-driven, custom-designed and motor-specific parameterization andoptimization.

PC For commissioning by means of IndraWorks, a conventional Windows PC isrequired.

Commissioning via NC Commissioning via the NC control unit requires access to all drive parame‐ters and functionalities.

Multimeter Troubleshooting and component checks can be facilitated by a multimeter al‐lowing the measurement of voltage, current and resistance values.

14.4 Parameterization14.4.1 General

IndraWorks allows entering or editing certain parameters and executing com‐mands during commissioning by means of menu-driven dialogs and list rep‐resentations or, optionally, via the control terminal.

14.4.2 Entering motor parameters

Motor parameters are specified by Rexroth and cannot bechanged by the user. If these parameters are not available, com‐missioning is not possible! In this case, please contact yourRexroth Sales and Service Facility.

Activation of the motor immediately after mo‐tor parameter input may result in injury andmechanical damage! The motor is not yetready for operation simply by entering themotor parameters!

WARNING

⇒ Enter parameters for length measuring system⇒ Check and adjust the measuring system polarity⇒ Configure the commutation settings

The motor parameters can be entered as follows:● Use IndraWorks to load all motor parameters.● Enter the individual parameters manually via the controller● Load a complete parameter set at serial machines via the controller or

IndraWorks

14.4.3 Motor parameter at parallal arrangementAre two linear motors operated in a control device, the following parametershave to be adjusted when commissioning:

Parameter Designation Adjustment factor

P-0-4016 Direct-axis inductance of motor x 0.5

P-0-4017 Quadrature-axis inductance of motor x 0.5

P-0-4048 Motor winding resistance x 0.5

S-0-0109 Motor peak current x 2

S-0-0111 Motor current at standstill x 2

Tab. 14-1: Parameter adjustment at parallel arrangement

A smaller controller can be used, if the maximum possible contin‐uous nominal force or the maximum possible peak force of themotor is not required. In this case, re-adjust the configured cur‐rents to the selected controller. Therefor, use Rexroth IndraSize(see Chapter 4.2 ).

14.5 Determining the polarity of the linear scaleIn order to avoid direct feedback in the velocity control loop, the effective di‐rection of the motor force and the count direction of the length measuringsystem must be identical.

Different effective directions of motor forceand count direction of the encoder systemcause uncontrolled movements of the motorupon switch-on!

WARNING

⇒ Secure against uncontrolled movement⇒Setting of the effective direction of the motor force identically to the countingdirection of the length measuring system

Effective direction of motor force The following applies for setting of the correct encoder polarity:The effective direction of the motor force is always positive in the direction ofthe cable connection of the primary part.

① Force directionFig. 14-2: Effective direction of motor force

Effective direction of the motorforce = Counting direction of the

length measuring system

In case of motion of the primary part in the direction of the cable connection,the counting direction of the length measuring system must also be positive:

The encoder polarity is always set in regard to the primary part(cable connection). The installation direction or pole sequence ofthe secondary part does not have any impact on the encoder po‐larity setting.

The encoder polarity is set via parametersS-0-0277, Position encoder type 1 (Bit 3)Position, velocity and force data must not be inverted when the length meas‐uring system count direction is set:S-0-0085, Torque/force polarity parameter: 0000000000000000S-0-0043, Velocity polarity parameter 0000000000000000S-0-0055, Position polarity 0000000000000000

14.6 Commutation adjustment14.6.1 General

The force of the synchronous linear motor can only develop to a maximumand constant degree, if the commutation angle is set correctly.

Commutation adjustment always has to be performed in the fol‐lowing cases:⇒ Initial commissioning⇒ Modification of the mechanical attachment of the linear scale⇒ Length measuring system replacement⇒ Modification of the mechanical attachment of the primary and/orsecondary part

This procedure ensures that the angle between the current vector of the pri‐mary part and the flux vector of the secondary part is always 90°. The motorsupplies the maximum force in this state.

Adjustment procedure Different commutation adjustment procedures have been implemented in thefirmware. The following figure shows the connection between the lengthmeasuring system used and the procedure to be applied.

With the above-specified settings, the effective commutation offset(P-0-0521) is automatically calculated on switching to operating mode. Thedrive is ready for power activation.

The procedure “Reference point optimum commutation offset”cannot be used in the case of analog Hall units, as the necessaryparameter P-0-0508 already uses the procedure “Commutationvia analog Hall units”.

Tab. 14-5: Parameters to be checked before commutation adjustmentWith the above-specified settings, the effective commutation offset(P-0-0521) is automatically calculated on switching to operating mode. Com‐mutation by means of digital Hall unit only enables reaching of an electricalaccuracy of +/- 30°. In this respect, a maximum power loss of 14 % is to beexpected.Hence the maximum motor force is available, a “Reference point optimumcommutation offset” must be stored on the reference point.Procedure at IndraDrive Cs:1. Activate initial commissioning mode (P-0-0522, bit 15)2. Carry out commutation adjustment using the sinusoidal procedure.3. Switch axis to "AF".4. Start fine commutation.5. Initiate reference point run.

If the reference point is reached, the "reference point of optimum com‐mutation offset" (P-0-0508) is placed there.

6. Deactivate initial commissioning mode.On each restart of the machine, the rough commutation offset (+/- 30°) is de‐termined by switching to operating mode. The drive may now run to the refer‐ence point with reduced force. If the reference point is reached or passed, theoptimum reference point for the commutation offset is applied by the driveand the maximum force is available to the axis.

14.6.4 Measuring procedure: Measuring of the relation between primary andsecondary part

For commutation setting, this procedure requires determination of the relativeposition of the primary part in relation to the secondary part. This procedurehas the advantage that commutation adjustment does not require any power

MCL Ironless Linear Motors 177/197

switching and axis motion. Commutation adjustment only needs to be carriedout on initial commissioning.

This procedure requires an absolute length measuring system.

Measuring of the relative positionof the primary to the secondary

part

Depending on the accessibility of the primary and secondary part in the ma‐chine or system, the relative position of the primary to the secondary partmay be calculated in different ways:

a Relative position reference point ①b Relative position reference point ②lp Primary part lengthFig. 14-5: Measuring of the relative position of the primary to the secondary

part

The position of the primary part must not be changed before theprocedure for commutation adjustment is completed!

Calculation of P-0-0523, Commu‐tation adjustment measured value

The input value for P-0-0523 that is required for calculating the commutationoffset, is determined from the measured relative position of the primary partwith respect to the secondary part (Fig. 14-5, distance a or b, depending onaccessibility), and a motor-related constant kmx (Fig. 14-6 and Fig. 14-6).

Activation of commutation adjust‐ment command

Prerequisites:1. The drive must be in status A0-13 during the following adjustment pro‐

cedure (= ready for power switching).2. The position of the primary part or the slide must not have changed after

measuring of the relative position of the primary to the secondary part.After the determined value P-0-0523 (Commutation adjustment measuredvalue) is entered, command P-0-0524 (D300 Commutation adjustment com‐mand) has to be started. In this process, the commutation offset is calculated.

If the drive is in command start "AB" (drive ready for operation),the commutation offset with the selected procedure (saturation orsinusoidal procedure) is determined for automatic commutation.

Afterwards, the command is to be cleared.

14.7 Setting and optimizing the control loop14.7.1 General procedure

The control loop settings in a digital drive controller have an essential impor‐tance for the properties of the servo axis. The control loop structure consistsof a cascaded position, velocity and current controller. Which controller is ac‐tive is defined by the operation mode.

Defining the control loop settings requires the corresponding ex‐pertise.

The procedure for control loop optimization (current, velocity and positioncontroller) at linear direct drives corresponds to the procedure for rotary servodrives. Only the setting limits of linear drives are higher.

Automatic control loop setting Rexroth drive controllers enable automatic control loop setting.Filtering mechanical resonance vi‐

brationsDigital drives from Rexroth are able to provide a narrow-band suppression ofvibrations that are produced due to the power train between motor and me‐chanical axis system. This results in increased drive dynamics with good sta‐bility.The mechanical system of the slide that is moved by the linear drive is stimu‐lated to vibrate mechanically due to the position and/or velocity return withinthe closed control loop. This behavior, known as "Two-mass vibrational sys‐tem", is mainly in the frequency range from 400 to 800 Hz. It depends on therigidity of the mechanical system and the spatial expansion of the system.

Page 189: MCL - Bosch Rexroth

In most cases, this "Two-mass vibrational system” has a clear resonant fre‐quency that can be selectively suppressed by a rejection filter installed in thedrive.When the mechanical resonant frequency is suppressed, the dynamic prop‐erties of the velocity control loop and of the position control loop may, undercertain circumstances, be improved as compared with closed-loop operationwithout rejection filter.This leads to an increased profile accuracy and shorter cycle times for posi‐tioning processes at a sufficient distance to the stability limit.Rejection frequency and bandwidth of the filter can be selected. The rejectionfrequency is the frequency with the highest attenuation. The bandwidth de‐fines the frequency range in which the attenuation is less than –3 dB. A high‐er bandwidth leads to less attenuation of the rejection frequency!

14.8 Maintenance and checking of motor components14.8.1 General

MCL motor components do not require any maintenance. During operation,however, external influences may cause damage at motor components. With‐in the service intervals of the machine or system, preventive checking of line‐ar motor components should be carried out.

14.8.2 Checking of motor and additional componentsThe following points should be observed and if necessary restored during thepreventive check of motor and auxiliary components:● Noticeable sound during operation● Scratches on primary and secondary part● Dirt (e.g. shavings, dust, grease by guides etc.) within the air gap be‐

tween primary and secondary part● State of power and encoder cables in a drag chain.● State of length measuring system (e.g. contamination)● State of guides (e.g. deterioration of linear guides)

14.8.3 Electrical check of motor componentsElectrical defects at a primary part are can be indicated in advance by meas‐uring the electrical characteristics. The following variables are relevant:● Resistance between motor connecting wires 1-2, 2-3 and 1-3● Inductance between motor connecting wires 1-2, 2-3 and 1-3● Insulation resistance between motor connecting wired and guides

Resistance and inductivity The measured values of resistance and inductance can be compared to thevalues specified in chapter "Technical data". The individual values of resist‐ance and inductance measured between the connections 1-2, 2-3 and 1-3should be identical within a tolerance of ± 5 %. There can be a phase shortcircuit, a fault between windings, or a short circuit to ground if one or morevalues differ significantly. If so, the primary part must be exchanged.

Insulation resistance The insulation resistance measured between the motor connection wires andground should be at least 1 MΩ (MegaOhm). If this value is fallen below, re‐placement of the primary part is recommended.

If necessary, please contact the Bosch Rexroth customer servicefor inspection of the electrical system.

14.9 Operation with third-party controllersRate of rise of voltage The electrical insulation of the motor is subject to a higher dielectric load in

converter mode than when it is operated with a merely sinusoidal source volt‐age. The voltage load of the winding insulation in converter mode is mainlydefined by the following factors:● Crest value of voltage● Rise time of pulses at the motor terminals● Switching frequency of final converter stage● Length of power cable to the motorMain components are the switching times of the final converter stage and thelength of the power cable to the motor. The rates of rise of the voltage occur‐ring at the motor may not exceed the pulse voltage limits specified inDIN VDE 0530-25 (VDE 0530-25):2009-08 (picture 14, limit curve A), meas‐ured at the motor terminals of two strands in relation to the rise time.

These limits are complied with by the final stages of IndraDriveconverters.
